What is Samsung 840?
The 840 series drive uses the new 3-bit-per-cell MLC NAND (also known as triple-level-cell or TLC NAND). In fact, it’s the first mass-production consumer SSD that uses this type of flash memory. A shortcoming of the 840 series is that TLC flash memory generally has lower write endurance than other type of SSD NAND.
What is the average SSD lifespan?
around 10 years
Current estimates put the age limit for SSDs around 10 years, though the average SSD lifespan is shorter. In fact, a joint study between Google and the University of Toronto tested SSDs over a multi-year period. During that study, they found the age of an SSD was the primary determinant of when it stopped working.
Does DRAM matter in SSD?
Unlike NAND flash, DRAM is volatile memory that must be powered on to hold data. However, DRAM is not a mandatory component of every SSD. Certain SSDs are sold without DRAM, making them suitable for customers on a tight budget.
Why are SSDs still so expensive?
SSDs are more expensive because they’re a newer, more modern technology. Rather than writing to a magnetic disc like an HDD, they store directly on chips, and thus are much faster, require less energy, and operate noiselessly. The trade off is the expense, which is steadily decreasing.
